Toallwhomit'rruiyconcern: v

Be it known that I, JAooB MARTIN, a citizen of the United States, andr'esiding a't- Brooklyn, in the county of Kings and State of New York,have invented certain new and useful- Improvements in Siphons, of"which.

the following 'is a specification, such as will enable those skilled inthe art to which it appertains to make and use the same.

This invention relates to siphons,*and the object thereof'is to provideimprovedmeans for regulating the pressure in vessels ofthis' class, orto revent the increase of said pressure beyonc a predetermined point.

The invention is fully disclosed in the following specification, ofwhich theaccompanying drawing forms apart, in which the separate partsofmy improvement are designated by suitable reference characters in eachof the views, and in which Figure ].'-is a side View of a siphonprovided with myimprovement; and, Fig. 2 ap'artial section onthe line 2-2 of Fig. 1.

In' the drawing forming part of this speci fication, I have shown. at athe topof a 'siphonor similar vessel to which is secured the usual neckmember 11 provided with a dis chargespout ,0 which communicatestherewith at' one side" thereofin the usual manner, and, in thepracticeof my invention, I connect with one side of the neck member I) below'thedischarge spout c a pressure regulating device d. The pressure regulatinde vice 1 comprises .a port (1 inclosed y a threaded neck (1 rovidedwith a threaded cap I), and placed in the neckd is a valve (1 adapted toclose the port d and between which and the cap (1, is. a spring (1?designed to hold the valve d? upon its seat and to close the port (1The'nec'k d is also pro' ort (I -which is located in v V such mannerthat it cannot be closed by the cap dfl and the pressure of the spring-don the valve d may be regulated at any time by turning the cap d. If thesaid pressure is to be increased'the oap' d is turned to the right,

1 and if it is desired to lessen said pressure, the

c'ap'd is turned to theleft and, in this way, 7

the pressure in the siphon or vessel 0 m y be regulated, as will bereadily understood,fit being apparent that whenever said pressureincreases be end a predetermined point the valve (i wi 1 be openedthereby and the ovarzpressure exhausted throughthe ports d an It is' awell known fact that siphons or,

other vessels of this, class are'frequently burst or destroyed by reasonof the in crease of pressure therein, but by means of my'improvementthis djfiiculty may be obviated; and although, I-have shown a pressureregulator or exhaust of specific form and construction, it will beapparent that various changes therein and modifications,

A siphon or similar device, the neck of which lS PIOVldGd with the usualdischarge spout and a' ressure exhaust. device connected with t e -neckbelow thedischarge spout, said device consisting of a port or pas sagein the side of the neck, an outwardly directed screw-threaded tubularcasing inclosiiig said port or passage and rovided ad'acent to said neckwith an out et, athrea ed cap screwed onto said casing, a valve withinsaidcasing for closin said port or passage, and a sprlng placed etweensaid cap and said valve.

In testimony that I claim the foregoing .as

my invention I have signed my name in presence of the subscribingwitnesses this 30th day of October 1907. V
